Patent ES-335292-A1 (ES)
Title: Non-woven filamentary structures
IPC: D04H3/16
Filed: 1967-01-05
Abstract: A non-woven fabric is made by forwarding a bundle of continuous filaments 38, see Fig. 1, under tension through a banding device 10 wherein they are aligned into parallel relationship as a ribbon, forming this ribbon into a diverging curtain of separated filaments, then overfeeding this curtain onto a receiving surface as it moves at right angles to the plane of the curtain thus forming the web. The banding device can comprise at least two non-parallel slots 18, and 22 with or without slot 20, covered by a plate (12) (see Fig. 2, not shown) so that streams of gas, e.g. air, passing through the slot align the filaments into the ribbon. The width of the ribbon can be regulated by adjustment of the air flow to the slots. Modifications of the shape and positions of the slots is illustrated in Figs. 3 and 4, not shown. The spreading device 40 which forms the filaments into the curtain can have a slot 44 which subjects the ribbon to a gas stream of arcuate cross section. The spreading device has an impingement plate (48), see Fig. 6 not shown, which may be adjusted so as to vary the width of the web. The web width may also be varied by adjustment of the relative positions of the banding device spreader and receiving surface. The filaments can be drawn or undrawn, or a mixture thereof can be used. The filaments can be heat-set during drawing. The filaments can be drawn before or after banding the filaments into a ribbon. The filaments can have any electrostatic charges removed by D.C. eliminators 58. mounted on either side of the running filament, see Figs. 7-10 not shown. The filaments can be made from polyethylene terephthalate, polyhexamethylene adipamide, polycaprolactam, polypropylene, dry viscose, cellulose acetate, acrylics and heterofilaments of various compositions. The filaments can be crimped. Binder filaments of lower melting point can be present, e.g. polyethylene isophthalate terephthalate copolymer. The web can be heated to bond the filaments, e.g. using hot calendering super-calendering.

Title: Device for electro-optically monitoring filiform material
IPC: B65H63/06
Filed: 1968-11-08
Abstract: The thickness of a running thread is measured by a photo-electric arrangement, the arrangement being such that while the thread is running it is kept pressed against the transparent cover 5 for the photo-cell 4 (position F 1 ), but if there is no movement in the longitudinal direction e.g. during insertion of the thread or when the thread has stopped, the tension on the thread is relaxed and it abuts against the end of prism 3 (position F 2 ), where it is held by air suction tubes 6, 7. In this latter position (F 2 ) the shadow of the thread thrown by light from at least two directions towards the photo-cell surface either falls outside the sensitive area of the cell or is minimal compared with the shadow for the thread in position F 1 and so a measurement signal is not produced. Instead of a single light source 1, a number of sources may be provided to give light beams falling on the thread from various directions. Instead of prism 3, a diffusing plate may be provided.
Patent ES-361364-A1 (ES)
Title: Process and apparatus for thermally treating flexible containers
IPC: A23L3/00
Filed: 1968-12-12
Abstract: In an apparatus for thermal treatment, e.g. sterilizing of products in hermetically sealed containers, the containers are passed as a train of mutually contacting units through an openended tube and are subjected to a thermal treatment while within said tube, the increased pressure within the containers resulting from the heating being compensated for. In one embodiment, containers, having lids heat-sealed thereto around their edges, are loaded into supporting moulds attached to successive carriers of a chain conveyer, a horizontal flight of which conveyer passes through an open-ended tubular channel. The supporting moulds are so shaped that they substantially seal the interior of the channel from the atmosphere, and support each other and hence also the ends of the containers. The channel includes sterilization and cooling sections where pressurized steam or hot water and cooling water, respectively, are introduced. - In the preferred embodiments, a vertical cylindrical tube 13 is used. As shown in Fig. 2, in which supporting moulds 28 holding the containers to be treated are fed into the top of the apparatus and discharged from the bottom, the tube 13 is roughly divided in sections as follows: a pressure building section 14, a secondary outlet 16 for treating medium leaking past a subsequent sealing section 17, a thermal treatment space 19 fed with steam or water, a sealing section 21, cooling space 22 supplied with cooling medium, a sealing section 25 for the cooling medium, and a discharge mechanism 27. The discharge mechanism 27 comprises a pneumatic ram operating in conjunction with a pair of pawls (39), Fig. 5 (not shown), that engage the underside of the top edge of the lowermost mould 28. Reciprocation of the pneumatic ram delatches the pawls from the lowermost mould 28 to lower the whole column of moulds 28 and relatch on the next lowest mould 28 in the column and thus removes the moulds 28 singly in turn. Dependent on the weight of the filled containers and supporting moulds 28, their weight alone may be sufficient to counterbalance the pressure build-up within the containers due to heat. Alternatively, a modified apparatus, in which the pressure building section 14 is replaced by a pressing mechanism (15), may be used. The mechanism (15), Figs. 3, 4 (not shown), utilises two pneumatic cylinder devices in conjunction with a latching mechanism to maintain a continuous pressure on the column including while loading it with moulds 28 singly as they are unloaded from the bottom of the column. The heating and cooling mediums may additionally be pressurized.
